If you just read the title and were wondering what the hell is a Chollima, we can say it is a winged horse, much like the Pegasus of Greek mythology.
Now, we are accustomed to weird and zany actions coming from the dictatorial North Korea, but a winged horse, that’s not even a real animal. The Chollima is a winged horse from Chinese mythology. It was said to be too swift and elegant for any mortal to mount. Following the Korean War, former North Korean leader Kim Il Sung devised the slogan “rush as the speed of Chollima,” as a way to invigorate his people into recovery efforts.
